locate - mouse selection of a set of points

### Calling Sequence

  `x=locate([n,flag])`

### Parameters

- `x`: matrix of size (2,n1). n1=n if the parameter n is given.
- `n,flag`: integer values.

### Description

`locate` is used to get the coordinates of one or more points selected with the mouse in a graphics window. The coordinates are given using the current graphics scale.

If n>0, n points are selected and their coordinates are returned in the matrix `x`.

If n<=0, points are selected until the user clicks with the left button of the mouse which stands for stop. The last point (clicked with the left button) is not returned.

x=locate() is the same as `x=locate(-1)`.

If `flag=1` a cross is drawn at the points where the mouse is clicked.
